1. PRODUCTION DESCRIPTION
1.1. Description
Loop Telecom’s TDMoE plug-in card is designed for the Loop-AM3440 series. TDMoE card is used to
transport TDM traffic over IP network, in addition to Ethernet traffic. As the communications network
migrates from TDM to IP, the TDMoE card provides a flexible and cost effective choice for the transport
of legacy TDM signals.
It provides four Ethernet ports with no limitation for WAN or LAN port assignment: two aggregate ports
with GbE combo interface and two tributary ports with 10/100/1000 BaseT Ethernet interfaces. The
TDMoE card support point-to-point and point-to-multi-point voice and date application.
For transport of TDM signals E1, T1, Jitter and Wander adheres to G.823 Traffic and G.823
Synchronous.
1.2. TDMoEthernet ─Theory of Operation
Over the past few years, packet-switched network (PSN) coverage has become ubiquitous, stimulating
a desire for convergence of all communications services over a unified infrastructure. This has brought
into prominence the concept of a pseudowire (PW). A pseudowire emulates a native service (e.g., ATM,
frame-relay, Ethernet or TDM) but utilizes transport over a PSN.
TDM over Ethernet, or TDMoEthernet, is a TDM PW technology that makes it possible to provision E1,
T1, and serial data services across IP, MPLS or layer 2 Ethernet networks. The services are provided in
a manner transparent to all protocols and signaling. TDMoEthernet enables service providers to
migrate to next generation networks while continuing to provide all their revenue-generating legacy
voice and data services, and without fork-lift upgrades of end-user equipment. TDMoEthernet also
benefits data carriers by enabling them to offer lucrative leased-line and voice services on their
packet-switched infrastructures. It enables enterprises to run voice and video over the same
IP/Ethernet-based network that is currently used to run only LAN traffic, thereby minimizing network
maintenance and operating costs.
Unlike other traffic types that can be carried over pseudowires, TDM is a real-time bit stream, leading to
TDMoEthernet having unique characteristics. In addition, conventional TDM networks have numerous
special features, in particular those required in order to carry voice-grade telephony channels. These
features imply signaling systems that support a wide range of telephony features, a rich standardization
literature, and well-developed OAM mechanisms. All of these factors must be taken into account when
emulating TDM over PSNs.
One critical issue in implementing TDM PWs is clock recovery. In native TDM networks the physical
layer carries highly accurate timing information along with the TDM data, but when emulating TDM over
PSNs this synchronization is absent. TDM timing standards can be exacting, and conformance with
these requires innovative mechanisms to adaptively reproduce the TDM timing. TDMoEthernet ensures
that recovered clock jitter and wander levels conform to ITU-T G.823/824, even for networks that
introduce high packet delay variation and packet loss.
TDMoEthernet complements VoIP in those cases where VoIP is not applicable, and in those cases
where VoIP price/performance is not optimal. Most importantly, TDMoEthernet can provide higher voice
quality with much lower latency than VoIP. And unlike VoIP, TDMoEthernet can support all applications
that run over E1/T1 circuits, not just voice. TDMoEthernet can provide traditional leased-line services
over IP, and is transparent to protocols and signaling. Because TDMoEthernet provides an evolutionary
(as opposed to revolutionary approach), investment protection is maximized.

CHAPTER 1 PRODUCTION DESCRIPTION

1.2.1. Clock Recovery
Sophisticated TDM clock recovery mechanisms, one for each E1/T1 interface, allow end-to-end TDM
clock synchronization, despite packet delay variation of IP/MPLS/Ethernet network.
TDMoEthernet supports the following clock recovery modes:
• Adaptive clock recovery
• External clock
• Loopback clock
The clock recovery mechanisms provide both fast frequency acquisition and highly accurate phase
tracking:
• Jitter and wander of the recovered clock are maintained at levels that conform to G.823/G.824 traffic or
synchronization interfaces. For adaptive clock recovery, the recovered clock performance depends on
packet network characteristics.
• Short-term frequency accuracy (1 second) is better than 16 ppb (using PPB reference), or 100 ppb
(using PPM reference)
• Capture range is ±90 ppm
• Internal synthesizer resolution of 0.5 ppb
• High resilience to the packet loss and mis-ordering, up to 5% of packet loss/misordering without
degradation of clock recovery performance
• Robust to sudden significant constant delay changes
• Automatic transition to hold-over is performed upon link-break events
1.2.2. Bundles
A bundle is defined as a stream of bits that have originated from the same physical interface. They are
transmitted from a TDMoEthernet source device to a TDMoEthernet destination device. For example,
bundles may comprise any number of 64 Kbps timeslots originating from a single E1, T1 or an entire
E3/DS3. Bundles are single direction streams, frequently coupled with bundles in the opposite direction
to enable full duplex communications. More than one bundle can be transmitted between two
TDMoEthernet devices. For E1/T1, the chip provides internal bundle cross-connect functionality, with
DS0 resolution. You can establish a cross-connect between different E1/T1 interfaces of TDMoEthernet
device, or within one interface of TDMoEthernet. Only one bundle can be defined for E3/DS3.
Up to 64 bundles are supported. Each bundle in the TDMoEthernet is transmitted using one of the
following payload type methods: AAL1, CESoPSN or SAToP. Each TDM over Ethernet
bundle/connection may be assigned to one of the payload types. For E1/T1, the chip provides internal
bundle cross-connect functionality, wit DS0 resolution. You can establish a cross-connect between
different E1/T1 interfaces of the TDMoEthernet device, or within one interface of the device.

3.2. LED
The front panel of the TDMoE has multi-color LEDs for operation and error indications. The indication is
either off, steady on, or flickering. The following table lists each LED and its color and the meaning it
represents. Note that when powering up and self test is in progress, the unit front panel LEDs are also
used to indicate fault conditions.

4. MAINTENANCE
4.1. Near End Loopback
The near end loopbacks such as backplane loopback, payload loopback, local loopback, and line
loopback, are activated by the TDMoE. The loopbacks are at the near end facility. The following
paragraph describes each loopback in detail.
4.1.1. Backplane Loopback/Time Slot Interface Loopback (FPGA to Backplane Loopback)
Backplane loopback is illustrated in Figure 4-1. The incoming signal is immediately looped back to
Backplane after entering FPGA without going through FPGA process. The outgoing signal then passes
TDMoE Chipset and Ethernet Switch and arrives in the remote physical link.
4.1.2. Payload Loopback (FPGA to Ethernet Loopback)
Payload loopback is illustrated in Figure 4-1. The signal is looped back to TDMoE Chipset from FPGA
after it goes through Ethernet Switch and TDMoE Chipset. The signal then passes Ethernet Switch and
arrives at the remote physical link.
4.1.3. Local Loopback (FPGA to Backplane Loopback)
Local loopback is illustrated in Figure 4-1. The incoming signal is looped back to Backplane from FPGA.
The outgoing signal then passes TDMoE Chipset and Ethernet Switch and arrives at the remote
physical link.
4.1.4. Line Loopback (TDMoE Chipset to Ethernet Loopback)
Line loopback is illustrated in Figure 4-1. The signal is immediately looped back to Ethernet Switch after
entering FPGA without going through FPGA process. The signal then arrives at the remote physical
link.

5. TERMINAL OPERATION
The TDMoE provides comprehensive report and configuration capability through the console port. By
using single-character commands and arrow keys, the TDMoE can be configured and monitored
through the use of a VT-100 terminal. The single-character commands are not case sensitive, except
for when using a password.
5.1. Log on and Log off
The Controller Menu screen will appear after you login. To Log off, simply press the Fbutton.
Note: The AM3440 chassis type will appear in the top left-hand corner of the screen.
(See highlighting in the sample screen below.)

PPb).
When a VT-100 terminal is connected to the CONSOLE port of the TDMoE, a main menu is displayed
on the VT-100 monitor. The main menu consists of four groups of commands, DISPLAY, LOG, SETUP,
and MISC. All commands are detailed in the VT-100 Menu Tree illustrations below.
